Description

Technical Field

[0001] The invention relates to the technical field of automobile door locks, and in particular to an integrated double-pull automobile side door unlocking mechanism. Background Art

[0002] As we all know, car door locks are one of the key safety components of a car, which is related to the car's driving safety, anti-theft performance, etc.

[0003] The basic functions of the car side door lock function include opening / closing, locking / unlocking, etc. Among them, when the occupant wants to open the car door with the door locked, the general operation is: first turn the lock button, unlock the door, and then pull the inner opening handle to open the door. This operation method is cumbersome on the one hand and requires different operations to be performed in two different positions, and on the other hand, it is not conducive to quick opening in an emergency.

[0004] As the number of cars in use increases, the appearance and interior layout of cars are also becoming more diverse. The diversification of car styling and layout can meet the aesthetic and functional needs of different people, bringing more sales and profits, but also poses a great challenge to the parts layout capabilities of automobile manufacturers. With consumers' demand for intelligent and convenient cars, electric release side door locks have begun to be used in the market, and people are paying more and more attention to the user experience of automobile products. In this environment, double-pull door opening saves the extra unlocking process, and because no additional mechanical structure is required, the interior of the door can also be more beautiful. Therefore, the double-pull method is increasingly favored by customers and major OEMs.

[0005] However, in the prior art, the double-pull unlocking mechanism of the side door lock generally needs to be equipped with two motors, one is an electric opening motor, and the other is a motor specifically used for the double-pull safety of the side door lock, so as to realize the double-pull safety of the side door lock. The above structure is relatively complex, with many parts, high cost, and limited use conditions.

[0006] Based on this, this application is specially filed. Summary of the invention

[0007] In view of this, the present invention aims to provide an integrated double-pull unlocking mechanism for a side door of an automobile, so as to solve the problems of complex structure and high cost of the double-pull unlocking mechanism for a side door lock in the prior art.

[0008] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0009] An integrated double-pull automobile side door unlocking mechanism, comprising:

[0010] A transmission gear, wherein the transmission gear can be driven to rotate by an electric motor;

[0011] an internal release lever capable of being pulled by a pull cord and returning to its original position when the pull cord is not in effect;

[0012] an inner locking coupling rod, wherein the inner locking coupling rod is connected to the second release rod through a torsion spring;

[0013] The inner locking rod comprises three limiting claws, namely a first limiting claw, a second limiting claw and a third limiting claw, wherein the first limiting claw can be driven by the transmission gear during rotation, the second limiting claw can be driven by the inner release rod when rotating, and the third limiting claw cooperates with the inner locking coupling rod to limit;

[0014] When the double-pull safety is in operation, the electric opening motor drives the transmission gear to rotate, thereby driving the inner locking rod to rotate. Under the action of the inner locking rod, the inner locking coupling rod rotates relative to the second release rod, so that the inner locking coupling rod is relatively disengaged from the inner release rod.

[0015] In the double-pull safety release working condition, when the inner release rod is pulled by the pull rope for the first time, the inner release rod drives the inner locking rod to rotate in the opposite direction relative to the safety on, and the inner locking coupling rod rotates to avoid the space after the inner locking rod rotates under the action of the torsion spring, and the inner release rod returns to its original position, and the inner locking coupling rod is connected to the inner release rod as a whole;

[0016] When the inner release lever is pulled by the pull rope for the second time, the inner release lever, the inner locking coupling lever and the second release lever rotate integrally.

[0017] The integrated double-pull automobile side door unlocking mechanism described in the present invention integrates the double-pull safety driving mechanism into the mechanism of the electric opening function, realizing the functions of electric opening and safety of the side door lock driven by one motor, saving a driving motor and corresponding accessories such as cables and mounting frames, optimizing the product structure, saving the installation space of the side door lock, improving the assembly efficiency of the product, and reducing the production cost of the product.

[0018] Furthermore, a first limit block is arranged on the transmission gear, and in a double-pull safety condition, the first limit claw can be driven by the first limit block during the rotation process.

[0019] The arrangement utilizes a transmission gear to drive the inner locking rod to rotate when the double-pull safety is in operation, and has a simple structure and reliable transmission.

[0020] Furthermore, the inner locking rod is sleeved on the first rotating shaft and can rotate relatively, the inner locking coupling rod is sleeved on the second rotating shaft, the inner locking coupling rod and the second release rod are connected as a whole through a torsion spring arranged at the second rotating shaft, the inner release rod and the second release rod are hingedly connected through a third rotating shaft, when the inner locking coupling rod couples the inner release rod and the second release rod as a whole, when the inner release rod is pulled by the pull rope to release the safety, the inner release rod and the second release rod rotate along the third rotating shaft.

[0021] The setting realizes the switching of the double-pull safety locking and double-pull safety unlocking functions of the side door lock by switching the inner locking coupling rod at different working positions. The structure is ingenious and the locking and unlocking functions are reliable.

[0022] Furthermore, the inner locking coupling rod includes a rotating body and a first limiting groove. In the double-pull safety working condition, the third limiting claw can extend into the first limiting groove during the rotation process to drive the inner locking coupling rod to move.

[0023] Furthermore, the rotating body is arranged in a V-shape as a whole, and the first limiting groove is an opening on the rotating body facing the third limiting claw.

[0024] This arrangement is convenient for the processing and manufacturing of the inner locking coupling rod, and also facilitates the reliability and stability of the inner locking rod driving the inner locking coupling rod to perform the double-pull safety operation.

[0025] Furthermore, the inner release rod includes a release rod body, a first pushing block is arranged on the release rod body, the second limiting claw includes a second claw body and a third limiting block, and the first pushing block is used for pushing the third limiting block to rotate when the inner release rod is pulled for the first time under the double-pull safety condition.

[0026] This arrangement improves the reliability and stability of the inner locking rod rotating to release the safety when the inner release rod is pulled for the first time under the double-pull safety release working condition, ensures reliable driving, reduces concentrated stress, and prolongs the service life.

[0027] Furthermore, a second limiting groove is provided on the inner release rod, and after the first pull is performed under the double-pull release safety condition, the inner locking coupling rod can extend into the second limiting groove, so that the inner release rod, the inner locking coupling rod and the second release rod are coupled as one.

[0028] Furthermore, the second limiting groove and the first pushing block are respectively arranged on opposite sides of the release rod body on the inner release rod.

[0029] This arrangement further optimizes the limiting structure in which the inner locking coupling rod couples the inner release rod and the second release rod into one. The structure is ingenious, saves the space occupied by the double-pull unlocking mechanism, and ensures that the double-pull unlocking mechanism is stable and reliable in unlocking.

[0030] Furthermore, a second limit block is arranged on the rotating body, and the second limit block is arranged on the side of the rotating body on the inner locking coupling rod away from the second limit groove. The second limit block realizes the switching of the double-pull safety working condition and the double-pull safety releasing working condition of the double-pull unlocking mechanism by disengaging from the second limit groove or snapping into the second limit groove.

[0031] Furthermore, the second limiting block is bent toward a side close to the second limiting groove.

[0032] This arrangement further improves the reliability and switching smoothness of the integrated double-pull automobile side door unlocking mechanism in the double-pull safety working condition or the double-pull safety releasing working condition, thereby increasing the service life.

Under the action of the inner locking rod 3, the inner locking coupling rod 5 rotates relative to the second release rod 10, so that the inner locking coupling rod 5 is relatively disengaged from the inner release rod 4.

[0056] In the double-pull safety release working condition, when the inner release rod 4 is pulled by the pull rope 8 for the first time, the inner release rod 4 drives the inner locking rod 3 to rotate in the opposite direction relative to the safety, and the inner locking coupling rod 5 rotates under the action of the torsion spring to avoid the space after the inner locking rod 3 rotates, and the inner release rod 4 returns to its original position, and the inner locking coupling rod 5 is connected to the inner release rod 4 as a whole;

The structure of the second release rod 10 unlocking during the pushing process is similar to or similar to the prior art, and will not be described in detail here.

[0059] The integrated double-pull automobile side door unlocking mechanism disclosed by the present invention integrates a double-pull safety driving mechanism into a mechanism of electric opening function, realizing the functions of electric opening and safety of the side door lock driven by one motor, saving a driving motor and corresponding accessories such as cables and mounting frames, optimizing the product structure, saving the installation space of the side door lock, improving the assembly efficiency of the product, and reducing the production cost of the product.

[0060] As a preferred example of the present invention, the inner locking rod 3 is sleeved on the first rotating shaft 6 and can rotate relatively, the inner locking coupling rod 5 is sleeved on the second rotating shaft 7, the inner locking coupling rod 5 and the second release rod 10 are connected as a whole through a torsion spring arranged at the second rotating shaft 7, the inner release rod 4 and the second release rod 10 are hingedly connected through a third rotating shaft 9, and when the inner locking coupling rod 5 couples the inner release rod 4 and the second release rod 10 as a whole, when the inner release rod 4 is pulled by the pull rope 8 to release the safety, the inner release rod 4 and the second release rod 10 rotate along the third rotating shaft 9.

[0061] This arrangement realizes the switching of the double-pull-up safety locking and double-pull-release safety unlocking functions of the side door lock by switching the inner locking coupling rod 5 at different positions. The structure is ingenious and the locking and unlocking functions are reliable.

[0062] As a preferred example of the present invention, the inner locking coupling rod 5 includes a rotating body 501 and a first limiting groove 502.

Preferably, the rotating body 501 is arranged in a V-shape as a whole, and the first limiting groove 502 is an opening on the rotating body 501 facing the third limiting claw 303.

[0063] This arrangement is convenient for the processing and manufacturing of the inner locking coupling rod 5 , and is also convenient for the inner locking rod 3 to drive the inner locking coupling rod 5 to perform the double-pull safety operation with increased reliability and stability.

[0065] This arrangement improves the reliability and stability of the inner release rod 4 in realizing the rotation of the inner locking rod 3 to release the safety when the inner release rod 4 is pulled for the first time under the double-pull safety release condition. The V-shaped first push block 402 and the arc-shaped third limit block 3022 ensure that the inner release rod 4 can drive the inner locking rod 3 to rotate reliably during the rotation process, and the driving is reliable, which reduces concentrated stress and prolongs the service life.

[0066] As a preferred example of the present invention, a second limiting groove 403 is provided on the inner release rod 4. After the first pull is performed under the double-pull release safety condition, the inner locking coupling rod 5 can extend into the second limiting groove 403, so that the inner release rod 4, the inner locking coupling rod 5, and the second release rod 10 are coupled as one. As a specific example of the present invention, the second limiting groove 403 and the first pushing block 402 are respectively provided on opposite sides of the release rod body 401, including opposite sides in the length direction and opposite sides in the rotation direction, that is, the second limiting groove 403 and the first pushing block 402 are provided diagonally along the length direction structure of the release rod body 401.

[0067] This arrangement further optimizes the limiting structure in which the inner locking coupling rod 5 couples the inner release rod 4 and the second release rod 10 into one body.

Preferably, the second limit block 5011 is bent toward the side close to the second limit groove 403.

[0069] This arrangement further improves the reliability and switching smoothness of the integrated double-pull automobile side door unlocking mechanism in the double-pull safety working condition or the double-pull safety releasing working condition, thereby increasing the service life.

[0070] As a preferred example of the present invention, the position where the pull cord 8 pulls the inner release rod 4 is set between the second limiting groove 403 and the first pushing block 402. As an example of the present invention, the position where the pull cord 8 pulls the inner release rod 4 is set in the middle position of the release rod body 401.

[0071] This arrangement further improves the reliability of realizing the double-pull safety unlocking function by pulling the inner release rod 4 by the pull rope.

[0072] Specifically, as an example of the present invention, Figure 1 , Figure 2 The example shown in the figure is an integrated double-pull automobile side door unlocking mechanism disclosed by the present invention. After the electric opening motor 1 is started, the transmission gear 2 is driven to rotate counterclockwise. During the rotation of the transmission gear 2, the first limit block 201 on the transmission gear 2 abuts against the first limit claw 301 on the inner locking rod 3, driving the inner locking rod 3 to rotate clockwise. During the rotation of the inner locking rod 3, the third limit claw 303 is inserted into the first limit groove 502 on the inner locking coupling rod 5, driving the inner locking coupling rod 5 to overcome the action of the torsion spring and rotate counterclockwise, so that the second limit block 5011 on the inner locking coupling rod 5 is disengaged from the second limit groove 403 on the inner release rod 4. At this time, the inner release rod 4 is in an empty state. When the inner release rod 4 rotates under the action of the pull rope 8, it cannot drive the second release rod 10 to move. At this time, the electric side door lock is in a locked state; when the door needs to be opened, such as Figures 3 to 8As shown, by pulling the pull rope 8 for the first time, the inner release rod 4 is driven to rotate counterclockwise, and the first pushing block 402 on the inner release rod 4 pushes the inner locking rod 3 to rotate counterclockwise during the rotation process. During the rotation process, the third limiting claw 303 disengages from the first limiting groove 502, and the inner locking coupling rod 5 rotates clockwise to the position where the inner locking rod 3 is vacated under the action of its own torsion spring. When the inner locking coupling rod 5 rotates under its own torsion spring, the second limiting block 5011 can be inserted into the second limiting groove 403 on the inner release rod 4, so that the inner release rod 4, the inner locking coupling rod 5, and the second release rod 10 are coupled as one, and the position where the relevant unlocking mechanism is triggered is reached. The inner release rod 4 returns to its original position under the action of the torsion spring at its rotating shaft (third rotating shaft 9); then the pull rope 8 is pulled for the second time to drive the inner release rod 4 to rotate counterclockwise, and the inner release rod 4, the inner locking coupling rod 5, and the second release rod 10 rotate counterclockwise as a whole, pushing the relevant mechanism at the lower end of the second release rod 10 to work, so as to open the door.
